Bird-repelling robot

Description

Bird-repelling robots are intelligent devices designed to deter birds using non-harmful methods, thereby reducing economic losses and safety hazards caused by birds in vineyards, cherry orchards, airports, farmlands, and other areas.

In actual cultivation, birds understand plant growth habits better than humans. This is particularly true for berry crops such as grapes, blueberries, and cherries; they detect ripening fruit earlier than humans, picking and eating them as they ripen, which causes significant economic losses for growers. To address this issue, growers have begun adopting various bird deterrence methods, including but not limited to manual scaring, scarecrows, mimicking the calls of natural predators, and bird netting. However, these methods generally suffer from low efficiency and high costs, and some may even harm the birds.

Bird-repelling robots, on the other hand, can accurately identify birds even in obstructed or low-light environments, and then drive them away using acoustic, optical, or other methods.

Parameter Table

Depending on the operating environment, bird-repelling robots may be equipped with one of two types of chassis: wheeled or tracked.

Wheeled chassis: Suitable for hard farmland terrain and ideal for operations on large-scale farms.

Tracked chassis: With a large contact area, these are suitable for operations in muddy, wet, sandy, or steep terrain.

Comparison Dimensions	Wheeled Chassis	Tracked Chassis
Terrain Adaptability	Flat/Hard Ground (such as farmland, airport)	Complex/Soft Ground (such as mountains, wetlands)
Obstacle Surmounting Capability	Low (less than 20cm obstacle)	High (greater than 30cm obstacle)
Energy Efficiency	Low (long battery life)	High (short battery life)
Maintenance Cost	Low (tire replacement is simple)	High (tracks are easy to wear and require professional maintenance)
Load Capacity	Medium (50-80kg)	High (greater than 100kg)
Speed	High (5-10km/h)	Low (2-6km/h)
Soil Impact	Easily compacted soil (hard surface required)	Disperse pressure (protect farmland)

Multi-dimensional bird-repellent technology combination

Acoustic deterrence

Biosound waves: Play the calls of birds of prey or the cries of birds, and propagate them directionally through speakers (frequency range 1-20kHz).

Ultrasound: Interfere with the auditory system of birds (frequency 20-50kHz), but avoid affecting other animals.

Optical deterrence

Laser scanning: Green lasers (532nm wavelength) form a dynamic light network above the farmland, and birds avoid it as obstacles.

Strobe lights: High-brightness LED lights flash at irregular frequencies (such as 1-10Hz), interfering with bird vision.

Physical deterrence

Smell spray: Spray natural repellents (such as methylanthrone, capsaicin) to drive birds away by smell, which must comply with agricultural safety standards.

Robot arm drive: Create irregular movements through swinging arms or wind wheels to simulate the activities of natural enemies.

Core functional requirements

The load capacity of the bird-repelling robot: it needs to carry sensors, bird-repelling equipment (such as sound and light transmitters, lasers), batteries, etc.

Battery life: using high-capacity lithium batteries or solar panels (such as top integrated photovoltaic modules) to support 8-12 hours of continuous operation.

Waterproof and dustproof: IP67 protection level, suitable for outdoor rain, snow, and dusty environments.

Typical agricultural scene adaptation and cases

Orchard planting (apple, cherry, grape, etc.)

Pain point:
Ripe fruit is vulnerable to damage from birds such as sparrows and crows.

Solution:
Deploy wheeled robots to patrol along the rows of fruit trees, with laser transmitters and sound wave equipment on the top.
Identify the maturity of the fruit through AI and dynamically adjust the intensity of bird repellent (such as high-frequency sound waves + lasers during maturity).

Case:
After using bird repellent robots in an apple orchard in Europe, the fruit loss rate dropped from 35% to 8%, saving 20,000 to 30,000 US dollars/year in manual bird repellent costs.
Berry and vegetable planting (blueberries, strawberries, open-air vegetables)

Pain points:
Small birds (such as tits) frequently peck, and traditional nets are expensive and affect light.

Solution:
The foot-type bird-repelling robot crosses narrow ridges and is equipped with a liftable sound and light device.
Infrared cameras and lasers are used at night to target nocturnal birds (such as owls).

Case:
A blueberry farm in the United States uses bird-repelling robots, combined with solar power supply, to reduce bird damage losses by 75% throughout the year.
Aquaculture (fish ponds, shrimp ponds)

Pain points:
Egrets and kingfishers prey on fish and shrimp, and traditional repelling requires manual 24-hour duty.

Solution:
The amphibious bird-repelling chassis (waterproof design) patrols along the coast, combining sound waves and directional water cannons to repel.
Detect night bird activities through thermal imaging.

Case:
After deploying robots in a fish pond in Guangdong, bird predation was reduced by 90%, and annual revenue increased by more than 30,000 to 40,000 US dollars.

Accessories

The performance and reliability of the bird-repelling robot chassis are highly dependent on the selection and integration of its core accessories, including mechanical structure, drive system, sensors, control system, power system, bird-repelling equipment, environmental protection components and user interaction interface.

Motor

Used to drive the propulsion system to ensure movement and maneuverability.

Sensors

Essential for environmental perception, including lidar for mapping, cameras for visual recognition, ultrasonic sensors for proximity detection and infrared sensors for obstacle avoidance.

Control system

Onboard processors such as Raspberry Pi, Arduino or NVIDIA Jetson Nano handle navigation algorithms, sensor data processing and motor control. Many systems support frameworks such as Robot Operating System (ROS) for modularity and advanced autonomy.
